It's a Happy Rain Cloud! This was Robyn's first circuit board design, and first time using KiCad. It rains rainbows with self-flashing LEDs. :) Great for all ages.

  • The 3 phases of the board

    Here is a photo of the 3 phases the board went through to get to the final design!

  • Silk Screen Change

    I wanted the whole cloud to be filled in, not just the outline so I changed it from this...

    To this!

    When we got them back from the board house the silk screen wasn't great so the final draft was importing this version, inverting it and making everything outside of it the silk screen.

  • Rain cloud Image

    So at first I wanted to make an umbrella with raindrops under it. Unfortunately I couldn't find any open source clip art of an umbrella that I liked and I'm not the best at drawing so trying to draw my own wasn't realistic. That is how I landed on the cloud. I found the image of the cloud and of the raindrops separately and sized them and put them together on paint.

    We went from that to this trying to get the raindrops to be the right size to fit the LEDs comfortably inside.

    Start with the switch!

    The design on this board is super simple so you can solder the components on in any order. Personally, I like to start with the switch.

    Next, solder on the LEDs
  • 3
    Finally the battery holder

    I made the holes for the battery holder snug so with a little pressure it should snap into place for easy soldering!

        *I like to add a bit of extra solder so the clouds eyes look nice and smooth.
